(7) Total number of devices (05A5H: 1 word)
Indicates the number of the slave devices to operate on the network specified by a
parameter setting request from the S controller. (Setting information)
(8) Number of online devices (05A4H: 1 word)
Indicates the number of the slave devices executing data input/output to and from the
DN311. (Execution information).
(9) Number of bit strobe devices (05A3H: 1 word)
Indicates the number of the bit strobe mode slave devices to operate on the network
specified by a parameter setting request from the S controller. (Setting information).
(10)Number of polling devices (05A2H: 1 word)
Indicates the number of the polling mode slave devices to operate on the network
specified by a parameter setting request from the S controller. (Setting information).
(11)Polling no-response device map (0594H to 0597H: 4 words)
Indicates the polling mode slave devices registered in the DN311 but not responding
to transmissions from it, bit per device. (ON = No response) The figures in Table 4-8
are slave device node addresses.
(12)Bit strobe no-response device map (0590H to 0593H: 4 words)
Indicates the bit strobe mode slave devices registered in the DN311 but not
responding to transmissions from it, bit per device. (ON = No response) The figures
in Table 4-9 are slave device node addresses.
Supplementary Note
• The slave devices which support both polling mode and bit strobe mode are counted as both
bit strobe devices and polling devices.
